Items can be combined only when we receive payment by money order mailed to our office. We cannot combine shipping through PayPal payments on eBay auction items because of the eBay/PayPal rules. We know some sellers may still combine shipping but they do so at their own risk because they cannot provide a tracking number for each individual item, as they must per the PayPal rules.. We will not combine shipments on PayPal payments even if you have a PayPal confirmed address. I'm sorry but there are no exceptions to this rule.
